According to one model, the rate at which an animal's heart beats varies with its weight. Smaller animals tend to have faster pulses, whereas larger animals tend to have slower pulses. The table below lists average pulse rates in beats per minute (bpm) for animals with various weights in pounds (lb). Use regression (or some other method) to find values for a and b so that f(x) = ax models these data. a= Weight (lb) 40 Pulse (bpm) 142 150 400 1000 2000 70 45 29 19 (Type an integer or a decimal rounded to two decimal places as needed.)
